Mid11 iMac

I've updated the OS as prompted by Apple since I purchased my iMac in 2011. I've also downloaded numerous software from the Apple Store, such as Anti-Virus, and others, (which I thought were compatible because they were in the Apple Store). Now I haven't always removed this software correctly because there hasn't been a "remove' button and now my iMac is so slow and unresponsive that it has become extremely difficult to use, such that it is has become a problem. Can anybody help me to get my Apple product back to a state which so enthralled me when I purchased it please?

I am a computer novice so exact instructions which relate to El Capitan are needed please.

Thank you.

Phil

Do the following:

Install El Capitan from Scratch

Backup if possible before continuing.

Restart the computer. Immediately after the chime hold down the Command and Rkeys until the Apple logo appears. When the Utility Menu appears:

Select Disk Utility from the Utility Menu and click on Continue button.

When Disk Utility loads select the volume (indented entry, usually Macintosh HD) from the Device list.

Click on the Erase icon in Disk Utility's main window. A panel will drop down.

Set the Format type to Mac OS Extended (Journaled.)

Click on the Apply button, then wait for the Done button to activate and click on it.

Quit Disk Utility and return to the Utility Menu.

Select Reinstall OS X and click on the Continue button.

Upon completion you can restore your data. If you were using third-party software you should restore them from their original distribution media. Do not install any anti-malware or system cleaning software since they are not needed.

Back up your Mac if you have not done so already. To learn how to do that please read https://www.apple.com/support/backup/. To learn how to use Time Machine read Use Time Machine to back up or restore your Mac.

Then, shut down your Mac and restart it in "Safe Mode". To learn how to do that please read: Try safe mode if your Mac doesn't finish starting up. Compare how your Mac works in Safe Mode to how it has been.

Then, restart normally. If the same problem returns, please read the section If an issue doesn't happen in safe mode for Apple's recommended actions.

Finally, you can temporarily create a new User Account, and log in to that account to determine if the problem also exists when logged in to that Account. To learn how to do that read How to test an issue in another user account on your Mac - Apple Support. When you are finished troubleshooting, you can remove the temporary User Account by following these instructions: OS X El Capitan: Delete a user. Before removing it, confirm you don't need any of the files you might have created in that Account.

Let me know what you determine.
